Really liked schematics…would like to see much more…much much more

Excellent App

I have been using this app literally for years! It is super user friendly, diagrams are excellent and very easy to understand, and all of the pin connections etc for making up your own cables are excellent and easy to read. I highly recommend this app to anyone, whether you are an electrician or diy'er! Money well spent for sure!

very simple diagrams

bought this thinking there was a lot of complicated options, but it only provides extremely basic wiring that you can find on the internet

Response from developer

We believe the description to be accurate as to which wiring diagrams are included. If there are additional diagrams you would like to see included please provide feedback to techsupport@cyberprodigy.com and we'd be happy to look at adding those in a future update.

Good but needs more

Nice to have it all in one place (an app) but it’s nothing that cannot be easily found online. Nice layout and easy to use but needs more diagrams or perhaps a way to pick what your installing and the app automatically lay out the wiring for you. For example, how is a 3 way stitch wired with 3 or more lights with power first to the lights. Or how about a 4 way with the same setup!
